Where did you hear that? I think it's obvious that the Superman reboot they are doing with Man of Steel is made for starting a JL shared universe... It would be a stupid move from WB making an apart Superman movie while a big JL project and other superhero movies are coming.. Didn't they learn anything from the success of Avengers?

Huh? That's what he is saying it will be a part of the JL project, not apart from as in separate.
